Two questions about how central the question of origins is to your core beliefs

[Paraleptopecten (Timothy Campbell)]

@Burrawang

new species ( in the sense taxonomic convention), arise through Natural Selection, no one I know has ever disputed that clear reality.

Then use consistent terminology. Do not claim that

@Burrawang

it is most often likely to be variation within the genetic pool of individuals within the snail population

@Burrawang

alleged intermediate forms between species in the Yorktown Formation and the recent are nothing of the sort, they are merely either variations within a specie, or variants with pathology, or completely different extinct species

and then that they are all within a “kind”. Use “kind” whenever you are referring to something other than the standard definition of species.

@Burrawang

taxonomists love to create and name new species, in reality they are merely slight variants within an existing already classified population, of that Genus.

A genus is not a population. It is a set of similar or closely related species of a convenient size for communicaticatory purposes. This is untrue and a slander against taxonomists.

@Burrawang

off on a tangent

I gave an example of where viable hybrids can form between different species that no one sane will claim are conspecific. That is abundantly relevant.

@Burrawang

think it is reasonable to expect that enough of them survived in the water and on floating log mats that would have been absolutely enormous in extent to account as ancestors of the extant invertebrates we see today.

Was the flood water saline? Then virtually all of the freshwater organisms died. If it was fresh, then virtually all of the marine organisms died. There is one endemically freshwater phylum known. Sessile terrestrial organisms and non-salt tolerant plants cannot survive being under a salty ocean.

@Burrawang

it is the God inspired Bible that tells us about ‘kinds’.

Yes. And defines them in a way that matches modern species, not made-up hyperevolving proto-kinds that solely exist to be able to fit more animals on the ark.

@Burrawang

Invertebrates surviving in bark and hollow logs is one thing but warmblooded birds and humans would have died of exposure and hunger long before the flood year had passed.

Slugs would die faster than birds.
